- The medical term cóccix is a direct loan from Greek, where it means 'cuckoo', because the bone's shape resembles a cuckoo's beak.
- In Spanish, the word rabo is used for 'tail', but using it to refer to a human 'tailbone' without the suffix -dilla can be misinterpreted as a vulgar slang reference to male anatomy.
- In some Spanish-speaking regions, the phrase caer de rabadilla is used to describe falling hard on one's backside, regardless of whether the tailbone is actually injured.
